Surround Amplifier Circuit with TDA7053

Perhaps the surround amplifier circuit below is an interesting circuit is made. For, making easy just by using the IC and electrolytic capacitor added 1 , we already can hear the strains of music with sound ( Front Left ,Right and surround Right , Left. In addition to listening to music , this amplifier is also very suitable for gamers who want good sound quality. Minimum voltage requred 9 volts and maximum of 15 volts. Power Output of each speaker 10 Watt with 4 ohm impedance.

Subwoofer Wiring Diagrams

A subwoofer or a complete loudspeaker, which is dedicated to the reproduction of low-pitched audio frequencies known as bass. The typical frequency range for a subwoofer is about 20–200 Hz for consumer products, below 100 Hz for professional live sound,and below 80 Hz in THX-approved systems. Subwoofers are intended to augment the low frequency range of loudspeakers covering higher frequency bands.

     Subwoofers are made up of one or more woofers mounted in a loudspeaker enclosure—often made of wood—capable of withstanding air pressure while resisting deformation. Subwoofer enclosures come in a variety of designs, including bass reflex (with a port or passive radiator in the enclosure), infinite baffle, horn-loaded, and bandpass designs, representing unique tradeoffs with respect to efficiency, bandwidth, size and cost. Passive subwoofers have a subwoofer driver and enclosure and they are powered by an external amplifier. Active subwoofers include a built-in amplifier.
